my gf has her Xfinity modem/router in her downstairs living room and she lives on the second floor, her mom doesn't want an Ethernet cord going all the way from the living room to her room so what ive done is put one of those wifi extenders with an Ethernet port on the bottom and plugged it in at the bottom of her stairs a room away from her modem/router i ran it all the way upstairs into her room into a second wifi router (for wireless vr which works great but thats just her local connection) then from the router to her pc, and let me tell you her connection sucks, her connection is constantly fluctuating and her discord freezes constantly probably every 20 min, idk what wifi plan her mom uses but im wondering what i can buy to improve this whole situation, i was thinking about those 200 dollar Xfinity mesh network extenders and run 2 of them from the living room to her room but idk if that'll help
